Advanced Client Management
Client Configuration Mode
The ovpn_getclient can produce two different versions of the configuration.
- combined (default): All needed configuration and cryptographic material is in one file (Use "combined-save" to write the configuration file in the same path as the separated parameter does).
- separated: Separated files.
Note that some client software might be picky about which configuration format it accepts.
Client List
See an overview of the configured clients, including revokation status:
docker run --rm -it -v $OVPN_DATA:/etc/openvpn kylemanna/openvpn ovpn_listclients
Batch Mode
If you have more than a few clients, you will want to generate and update your client configuration in batch. For this task the script ovpn_getclient_all was written, which writes out the configuration for each client to a separate directory called clients/$cn.
Execute the following to generate the configuration for all clients:
docker run --rm -it -v $OVPN_DATA:/etc/openvpn --volume /tmp/openvpn_clients:/etc/openvpn/clients kylemanna/openvpn ovpn_getclient_all
After doing so, you will find the following files in each of the $cn directories:
ca.crt
$cn-combined.ovpn # Combined configuration file format. If your client recognices this file then only this file is needed.
$cn.ovpn # Separated configuration. This configuration file requires the other files ca.crt dh.pem $cn.crt $cn.key ta.key
$cn.crt
$cn.key
ta.key
Revoking Client Certificates
Revoke client1's certificate and generate the certificate revocation list (CRL):
docker run --rm -it -v $OVPN_DATA:/etc/openvpn kylemanna/openvpn easyrsa revoke client1
docker run --rm -it -v $OVPN_DATA:/etc/openvpn kylemanna/openvpn easyrsa gen-crl
The OpenVPN server will read this change every time a client connects (no need to restart server) and deny clients access using revoked certificates.
